Bring STEP product geometry into USD scenes
A STEP-to-USD pipeline combines STEP reading, scene preparation and the USD Import & Export SDK. The writer supports USD, USDZ and USDA. Use this route when engineering geometry needs to participate in a scene-based visualization or collaboration workflow.
Input STEP data can contain BRep and mesh representations. Tessellate BRep faces for mesh-based delivery and retain suitable mesh data already present. Decide how the assembly becomes a scene hierarchy and which source identifiers should become names or metadata.
Map engineering information to scene content
The USD component supports meshes, primitives, names, hierarchy, colors, metadata, materials and animations in both directions. A STEP conversion can transfer only the properties available from its reader and application document; it does not create animation or material definitions that the source never supplied.
For example, an assembly portal may need part names, placements and colors. A larger scene pipeline may add application-owned metadata or animation after reading the CAD model. Keep those enrichment steps explicit so the workflow can distinguish source information from newly authored content.
Select and verify the destination
Specify USD, USDZ or USDA output along with the receiving application. Reopen the scene there and compare orientation, scale, part positions, mesh quality and mapped attributes. Review any resources needed for the selected packaging.
Mesh generation is configurable through Express Mesh or a suitable BRepGraph Advance workflow. The retained engineering source remains the reference when later operations require precise BRep geometry.
